Can't set attribute error when trying to get cert

[schoen]

@TheHelpSeeker46

Hint: The Certificate Authority failed to download the challenge files from the temporary standalone webserver started by Certbot on port 80. Ensure that the listed domains point to this machine and that it can accept inbound connections from the internet.

This happens even when I use "sudo certbot certonly --nginx"

That error looks like it would come from sudo certbot --standalone rather than sudo certbot --nginx; do you get a different error from the latter?
